sEAM FOR METAL REGEPTACLES,

Specification of Letters Patent.

Application filed February 11, 1915; Serial No. 7,626.

To all whom it may concern.-

of lVisconsin, have invented a new and useful Seam for Metal Receptacles, of which the following is a specification.

This invention relates to seams for metal receptacles such as tanks, cans, pails, and the like, one of the objects of the invention being to provide a simple and efficient means for attaching the top or bottom of a tank or other receptacle to the metal wall thereof, it being possible to get a water-proof joint without the use of solder such as heretofore required.

lVith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawings, the preferred form of the invention has been shown. In said drawings-Figure 1 is a horizontal section through a portion of a can having the present improvements combined therewith. Fig. 2 is an enlarged section on line AB Fig. 1. Fig. 3 is a perspective view of portions of the joint separated.

Referring to the figures by characters of reference, 1 designates the sheet'metal wall of a receptacle, the same being provided with an outstanding flange 2 formed with concentric corrugations 3. Said flange merges at its outer edge into a flat ring-like base 4 which extends inwardly beyond the wall 1 and is bent upwardly'and outwardly to provide a rib 5. From this rib extends a flange 6 which is depressed relative to the top of the rib and is formed with radial corrugations 7 The flange 6 rests upon the base ring 4 and the corrugated portion thereof is adapted to support the depressed marginal portion 8 of the plate 9 constituting the top or bottom of the receptacle. The annular shoulder 10 formed by depressing the marginal portion 8 is adapted to engage the annular shoulder 11 formed by depressing the flange 6 so that when the depressed portion 8 is bearing on the corrugations 7 the shoulder 10 will bear inwardly against the shoulder 11, as shown in Fig. Bearing on and supported by the annular portion :8 of the .plate 9 is a washer or gasket 12 formed of fiber or any other suitable material and this gasket is adapted to be contacted by the annular corrugations 3 on the flange 2. Thus it will be seen that by inserting rivets through the flanges 2 and G, the base ring 4 and the gasket 12, the various parts can be clamped tightly together, the corrugations Patented F b. 1; 191 .1

3 all biting into the gasket while the corrugated flange 6 provides a yielding support for the depressed portion 8 of the plate 9.

Thus positive sealing of the joint is insured as an air and water tight connection is provided at each point of contact between the corrugations 3 and the gasket 12. The rivets have been indicated at 13.-

It is to be understood that the gasket 12 can be made of any desirable materialcapable of yielding under the binding action of the corrugations thereagainst.

What is claimed is:

1. A seam for metal receptacles, including a base ring having an annular upstanding bead, an annular flange extending from the bead and having radial corrugations bearing on the basering, a plate bearing upon the bead and having a depressed marginal portion bearing upon the corrugated flange, a flange integral with the outer edge of the base ring and having an annular corrugation, said last named flange overhanging the depressed marginal portion of the plate, a gasket interposed between said depressed marginal portion and the last named corrugated flange, and means extending through the flanges, gasket, depressed marginal portion and base ring forbinding the parts together. p j I 2. A seam for metal receptacles, including a base ring having an upstanding bead at its inner edge, a flange extending outwardly from the bead and having radial corrugations constituting a yieldable support for engaging the base ring, a plate having a upper and lower yieldable members, a plate right angles to the corrugations of the other 10 extending therebetween and resting upon one member. of vthe members, a gasket supported by the In testimony that I claim the foregoing as plate and contacted by the other yieldable my own, I have hereto affixed my signature 5 member, means extending through the plate, in the presence of two Witnesses.

members and gasket for binding them to- JOHN F. LESLIE. gether, each of said yieldable members being Witnesses:

members being disposed substantially at H. H. BUSHNELL.
